- FILENAME: Z80A.H;
- VERSION: 0.0;
- DATE: 10/11/1988;
-
- DESCRIPTION: "This program lets you use your computer to assemble
- code for the Intel 8080/Z80 family of microprocessors.
- The program is written in portable C rather than BDS
- C. All assembler features are supported except
- relocation, linkage, and macros.";
-
- KEYWORDS: Software Development, Assemblers, Cross-Assemblers,
- Intel, Zilog, Z80;
-
- SYSTEM: CP/M-80, CP/M-86, HP-UX, MSDOS, PCDOS, QNIX;
- COMPILERS: Aztec C86, Aztec CII, CI-C86, Eco-C, Eco-C88, HP-UX,
- Lattice C, Microsoft C, QNIX C;
-
- WARNINGS: "This program has compiled successfully on 2 UNIX
- compilers, 5 MSDOS compilers, and 2 CP/M compilers.
- A port to Toolworks C is untried."

- QBAL Z80 cross-assembler by Michael G. Panas.
-
- This header file contains the global constants and data type definitions for
- all modules of the cross-assembler. This also seems a good place to put the
- compilation and linkage instructions for the animal. This list currently
- includes the following compilers:
-
- Compiler Name Op. Sys. Processor
-
- 1) Aztec C86 CP/M-86 8086, 8088
- MSDOS/PCDOS
-
- 2) AZTEC C II CP/M-80 8080, Z-80
-
- 3) Computer Innovations C86 MSDOS/PCDOS 8086, 8088
-
- 4) Eco-C CP/M-80 Z-80
-
- 5) Eco-C88 MSDOS/PCDOS 8086, 8088
-
- 6) HP C HP-UX 68000
-
- 7) Lattice C MSDOS/PCDOS 8086, 8088
-
- 8) Microsoft C MSDOS/PCDOS 8086, 8088
-
- 9) QNIX C QNIX 8086, 8088
-
- Further additions will be made to the list as users feed the information to
- me. This particularly applies to UNIX and IBM-PC compilers.
-
- Compile-assemble-link instructions for this program under various compilers
- and operating systems:
-
- 1) Aztec C86:
-
- A) Uncomment out the "#define AZTEC_C" line and comment out all
- other compiler names in Z80A.H.
-
- B) Assuming that all files are on drive A:, run the following sequence
- of command lines:
-
- A>cc Z80A
- A>cc Z80Aeval
- A>cc Z80Autil
- A>ln Z80A.o Z80Aeval.o Z80Autil.o -lc
- A>era Z80A*.o
-
- 2) Aztec CII (version 1.06B):
-
- A) Uncomment out the "#define AZTEC_C" line and comment out all
- other compiler names in Z80A.H.
-
- B) Assuming the C compiler is called "CC.COM" and all files are
- on drive A:, run the following sequence of command lines:
-
- A>cc Z80A
- A>as -zap Z80A
- A>cc Z80Aeval
- A>as -zap Z80Aeval
- A>cc Z80Autil
- A>as -zap Z80Autil
- A>ln Z80A.o Z80Aeval.o Z80Autil.o -lc
- A>era Z80A*.o
-
- 3) Computer Innovations C86:
-
- A) Uncomment out the "#define CI_C86" line and comment out all
- other compiler names in Z80A.H.
-
- B) Compile the files Z80A.C, Z80AEVAL.C, and Z80AUTIL.C. Link
- according to instructions that come with the compiler.
-
- 4) Eco-C (CP/M-80 version 3.10):
-
- A) Uncomment out the "#define ECO_C" line and comment out all
- other compiler names in Z80A.H.
-
- B) Assuming all files are on drive A:, run the following sequence of
- command lines:
-
- A>cp Z80A -i -m
- A>cp Z80Aeval -i -m
- A>cp Z80Autil -i -m
- A>l80 Z80A,Z80Aeval,Z80Autil,Z80A/n/e
- A>era Z80A*.mac
- A>era Z80A*.rel
-
- 5) Eco-C88:
-
- A) Uncomment out the "#define ECO_C" line and comment out all
- other compiler names in Z80A.H.
-
- B) Compile the files Z80A.C, Z80AEVAL.C, and Z80AUTIL.C. Link
- according to instructions that come with the compiler.
-
- 6) HP-UX (a UNIX look-alike running on an HP-9000 Series 200/500,
- 68000-based machine):
-
- A) Uncomment out the "#define HP_UX" line and comment out all
- other compiler names in Z80A.H.
-
- B) Run the following command line:
-
- . cc Z80A.c Z80Aeval.c Z80Autil.c
-
- 7) Lattice C:
-
- A) Uncomment out the "#define LATTICE_C" line and comment out all
- other compiler names in Z80A.H.
-
- B) Compile the files Z80A.C, Z80AEVAL.C, and Z80AUTIL.C. Link
- according to instructions that come with the compiler.
-
- 8) Microsoft C (version 3.00 --> version 5.1):
-
- A) Uncomment out the "#define MICROSOFT_C" line and comment out all
- other compiler names in A68.H.
-
- B) Run the following command line:
-
- C>cl Z80A.c Z80Aeval.c Z80Autil.c
-
- 9) QNIX C:
-
- A) Uncomment out the "#define QNIX" line and comment out all other
- compiler names in Z80A.H.
-
- B) Run the following command line:
-
- . cc Z80A.c Z80Aeval.c Z80Autil.c
-
- Note that, under CP/M-80, you can't re-execute a core image from a previous
- assembly run with the "@.COM" trick. This technique is incompatible with the
- Aztec CII compiler, so I didn't bother to support it at all.
